POLE FIXTURE FOR ELECTRICAL CONDUCTORS Filed Aug. 12, 1951 .[zzzzew/or Patented May 30, 1933 UNITED STATES PATENT OFFICE ROLLAND G. WILLIAMS, BRANFOBD, CONNECTICUT, ASSIGNOR TO MALLEABLE IRON FITTINGS COMPANY, OF BRANFORD, CONNECTICUT, A CORPORATION OF CONNECTI- CUT POLE FIXTURE FOR ELECTRICAL CONDUCTORS- Application filed August 12, 1931. Serial No. 556,705.

My invention relates to pole fixtures for electrical conductors and has for its object to improve and simplify the construction shown in my Letters Patent No. 1,754,924,

" issued April 15, 1930 In the accompanying drawing,

Figure '1 is a front elevation showing the Figure 3 is a section at the line 33 of Fi ure 1.

imilar numerals of reference will be used to denote like parts in the several figures of the drawing.

1 is the pole and 2 is the base portion of the fixture whose rear is hollow and diverges both vertically and laterally and is provided with feet 3 at the top and bottom which are spaced apart and are curved to fit the pole, so that the fixture has four points of contact with the pole.

The fixture has a bolt 4 passed through its center and through the pole, which bolt is secured in the usual manner by a nut at the rear of the pole, not shown in the drawing. In the front face of this fixture at the top portion is a circular groove 5 which extends horizontally throughout the length of the fixture and in the bottom portion of the latter is a V-shaped channel 6 which isparallel with said groove. f

7 is a clamping member which has a groove 8 in its upper inner face that is complementary to thegroove 5, and has a V-shaped rib 9 in its lower inner face that is parallel with the groove 8. i V

The upper edge of the member 7 has a centrally disposed lip 10 that extendsinwardly; In applying the device for use, the fixture 2 is first secured to the pole the cable or conductor is then placed within the groove 5 and the member 7 then applied so that its groove 8 contains the cable or conductor A while the lip 10 overlaps the base fixture and the rib 9 engages within the channel 6, so that it will be seen that the cable orconductor is uniformly embraced without any danger of the strands thereof being cut or mashed by the clamplng members. Bolts 11 are then passed through the ends of the base fixture and member 7 and these parts firmly clamped together,

by nuts 12 driven on the ends of the bolts.

It will thus be readily seen that thebase I fixture is firmly contacted with the pole by means of the spaced diverging feet 3, thus doing away with any vertical extensions from said fixture and the securing thereof to the pole while the lip 10 and rib 9 hold the clamping member so that it cannot possibly skew and thereby cause the cable or'conductor to be cut or mashed when the nuts 12 are driven.

It has been ascertained that the lip 10 is necessary in addition to the bottom channel and V-shaped engaging part, and, moreover this lip affords a seat, in the event that an insulating protection bar is employed.

WVhat is claimed is Apole fixture for electric conductors com- 7 face and a lower shallow groove parallel to the upper groove, a clamping plate having a groove complementary to the firstgroove and having a lip extended outwardly from its upper side and lapping the top wall of the body and further having va V-like rib which extends into the lower groove, and a bolt extending through the clamping member and through the front wall of the body, and dis posed centrally of the length of the lip and in the space between said grooves.

- In testimony whereof I alfixmy signature hereto.
